Thanks for all your help. You have saved me so much time and work. I have never been a person who understands all the legal aspects of a contract.
The first time I rented my house out I thought I was so prepared. I had written the contract myself and each tenant signed it. A month later I did not receive any payments from any of the tenants. Apparently there was a huge mistake on the contract whereby the tenants found a loophole and got away with not paying rent. Thank you for teaching me how to become a wise landlord.
